A complete re-install of web server
I was wrong about the end of nightly downtimes, and I’m sorry. In fact, the situation got somewhat worse tonight. At around 3 AM (GMT time), the web server log script failed to start up the proxy web server - the same error that had been haunting me previously as well. I was able to get the server back up and running around 6 AM (GMT time).
Obviously I had had enough of these errors already. Thus I decided to take down the whole main web server for a complete re-install to get rid of these errors once and for all. It took me and DreamHost (they were a huge help for me, thanks folks!) a little over an hour to get it back up and running. The server is now lean and clean, running in a complete fresh environment.
All Listhings services are now operating normally, and I will be keeping a very close eye on the web server during the next days to make sure nothing like this would occur again!
Update: even though there have been downtimes, I would like to point out that these downtimes did not pose any risk whatsoever to your notes at Listhings. All your data is safe, and backed up.
